Earns its place in the Blender library as a focused utility for keeping object and data names in sync, either automatically or through a manual operator.
Auto Sync Object Data Names is a Blender add-on from GeeDoubleU that keeps object data names aligned with their object names. When you rename an object, the add-on renames the linked data block to match, and you can add a custom prefix to new object data names.
The add-on handles object data shared by multiple objects, letting you choose to rename it whenever a user is renamed or leave it unchanged, with an optional warning when data has multiple users. You can also disable specific object types, such as Meshes, Curves, Lights, and Cameras, so only the types you want are affected.
Alongside automatic syncing, it includes an operator to manually sync names for multiple objects in Object Mode, reached through the Object menu or the right-click menu. You can affect selected objects or all objects in the blend file, include children recursively, or use Inverse to replace an object's name with its object data name. Inverse follows the Affected Object Types preferences.
Auto Sync Object Data Names is best for blender users who want object data names to stay consistent with object names, with control over prefixes, affected object types, and multi-user data.
Auto Sync Object Data Names is completely free to download and use.
Auto Sync Object Data Names lists compatibility with Blender 4.2 LTS and newer. The developer also notes that Blender 4.0.0 or later is recommended, and that the add-on may work on earlier Blender versions, though no support is provided if it does not function fully. Version 1.0.0 is the current release, last updated on July 1st, 2025. If you run an older build you can try it, but for reliable behaviour the developer's guidance points to Blender 4.0 or newer, with 4.2 LTS and later officially covered.
Auto Sync Object Data Names installs through Blender's standard add-on flow. Download the .zip file from the GitHub repository, open Blender, and go to Edit > Preferences > Add-ons. Click Install from Disk from the dropdown at the top right, then select the downloaded .zip file to install it. You can also drag and drop the file into Blender. Once installed, the add-on's preferences appear under Edit > Preferences > Add-ons > Auto Sync Object Data Name; they are hidden by default, so click to expand the dropdown menu.
Auto Sync Object Data Names handles object data shared by multiple objects through its Multi-User Behavior setting. The Rename option renames the object data every time one of its users is renamed, while Do Nothing leaves shared data names unchanged. A separate warning option can display a message when object data is shared among multiple objects, or stay disabled so no warning shows. These settings live in the add-on preferences, letting you decide how synchronization behaves when a single data block is linked to more than one object.
Auto Sync Object Data Names is listed as free in this catalog, and it is released under the GNU General Public License v3.0 or later. The extension does not require special permissions. The add-on has been downloaded more than eleven thousand times and carries a rating from fourteen reviews, so you can review community feedback before installing.
